Zusammenfassung: Doble Engineering Company is a leading global provider of knowledge, diagnostic techniques and instruments for testing and condition assessment of high voltage apparatus.

The seminar will give a brief review what Doble can offer with special focus on a Transformer Health Review Model. The presentation will cover both the model and diagnostic techniques on which it is based. In this way a utility will be able to manage capital replacement strategy and transformer reliability by using advanced diagnostics and building a transformer health review.Doble Power Test (DPT) in UK has developed the Transformer Health Review Model with special algorithms and using this to make a total assessment of transformers belonging to a number of clients, best reference being National Grid in UK. The method is simple to establish, flexible to extend. It gives a very simple presentation of which transformers are critical seen from a reliability point of view, which should be investigated further, and which ones are without problems.

The model takes into account historical and design information, results of DGA and online assessments and is followed up with a complete set of off-line tests on those transformers where issues have been revealed.

Where many companies today are struggling with establishing large asset management systems, the Transformer Health Review is a flexible model, easy to test out in small scale.

DPT can offer to do the complete job as a consultant work or train the utility to do the job themselves, inclusive the necessary testing.
